Application filed August 8, 1910. Serial No. 576,027. i

To all whom, it may con/com:

Be it known that I, .Vrnnnnr l-l'nuuv Ber-win, of Vivian street, in the city of Nellington and Dominion of New Zealand hu'vc invented a new and useful Circulanl ushion ing Knitting'hlnchino Using Double-Ended Latch-Needles, of which the following is a specification. I

This invention relates to n knitting machine of the circular type for the production of tubular seamless hosiery and has for its primary object the provision of means which will enable the machine to nuniul'acture socks or stockings more exi 'ieditiouely and with a minimum amount of wear and tear as compared with the machines at present in use.

A leading feature of the invention is its entire simplicitv of construction and consequent small cost of production which will render the machine salable to small manulhc invention is such that it commences its manufacture at the top of the sock or stocking and terms the leg with a full com plement of needles by a circular or rotnry action till it reaches the heel and too which knitting the same upon approximately one half of the full complement of needles by a. reciprocating action and. reducing the number of needles in action at each course until a minimum number of needles rcnniin thcn reintroducing them again into action when a pouch or pocket for the heel and tools termed. The operation oi narrowing and wnlemng' iSRarried out automatitmlly by the mechanism upon the manipulation ot certain de vices arranged conveniently upon the out side of the machine while the action of transferring from rib to plain knitting and vice verso cllccted autmnatically by the machine upon the manipulation of certain levers on the outside of the machine.

In carrying: those o'ujects into eli'ect the construction coiumriscs briefly two specially constructed needle cylinders disposed endwise relatively to each other in a vertical position, the upper eylimlcr being held in position by an 'arched member or bridge connected to the body of the machine while the lower cylinder is disposed to e slight vertical movement; which serves to vary the 1 tension of the machine.

The lower needle-cylinder which is provided with webhelders and needle "jacks of special construction is contained within a circular member to he termed the body portion of the machine, which latter is pro vided with special cams and ncedleu'accs and is revoluhly mounted within a circular box to be called the body-holder, the lower portion of which forms a bearing tocthe lower cylinder while a cam box provided with special cams and comprising :1 semi circular shaped shell which portly encircles l the lower cylinder uttuched to the body and rotates around the cylinder when the machine is set in motion.

The upper cylinder which is provided with hectic-jacks ot special construction and is used for (loin; ribbing work is conwith all the necessary appliances such as the various ltinds of com-devices and needleraccs to he .rltwward referred to, while the inside of the cylinder is provided with an :uljostahlc tension ring which projects beyond the lower end of the cylinder and is disposed to a slight vertical movement whichserves to alter thetension oi the ribbing I work by varying the distance het-weci'i the l upper and lower cylinders.

The invention, of which the foregoing is simply a rough outline of its construction, will now be fully described and explained with reference to the accompanying sheets \tnined within a circular cam-box providedof drawings in which Figure is a front elevation of the mechine showing the outside of the lower cmnbox. Fig. is u vertical sectional view oi the machine. Figs. 3 end 43- are rcspec 1 lively outside and inside views of one hnl't' of the upper (lulll-lXlX, Figs. 5 and 6.- are rc.-:pectirclv outside and inside views of the l other hall' ot the upper cum-box, Fig. 7.- l is it view of the ins de of the lower cumlhox showing: the means for narrowing and widcningr to form the heel and too, Fig. 8.- is a view of the body of the machine with the arched member broken away l for convcniciu-e.

fIn carrying out this invention 1 is the body-holder comprising a circularshell or box having an outwardly ertending lug 2 'from its periphery which servesto support free to move longitudinally therein. The

the holder upon a bench or such like 3, and a'hangmgmember or lug 1. which serves to provide a beariiig for the driving spindle.

5 of the machine. The body-holder 1 of sufficient depth to provide a bearing surface for the lower needle cylinder 6 which is adapted to fit within the holder so as to be body-holder 1- is provided at its upper end with a ballbearingrace 7 by means of which the body .8 F ig.,8) which'rests within the holder, may be free to rotate.

The lower cylinder 6 .(Fig. 9) comprises three parts viz. an upper portion 6 which is provided with a longitudinal arrangement of parallelgrooves or channels 9 which serve as bedsfor the needles whichare of the ordinarydouble-ended latch type ajiniddle portion'6 ,,which is provided with a longitudinal arrangement of slots; 10 which are alternately situated with the 'needle-grooves 9 and through which the' projections 11 of the Web-holders l2that are contained within'thecylinder, are adapted to extend, while the thirdor lower portion 6 serves to guide the cylinder in its longitudinal-movement "Within the-body-holder, a feather-way 13 being provided which f'preventsany turning movement'of the cyliii'dernli j The top, end of the cylinder is. provided with-an annularcap or plate 14 which is formed with a radial arrangement of slots 15 that correspond with, the" slots- 10 and serve as guides for the top ends of the web holders 12, while the central opening is usedas a hopper for passing lthe work into a delivery tube 16 {that extends upwardly through the center of the cylinder and-is attached to the underside ;of the plate, 14;?

' Constructed in the middle pout-ion of the cylinder 6 around its ;per1phe1j is'a recess .17 within which a cam-ring 18 is'adapted to travel, the cam 18 serving to depress the projections 11 of the web-holders12-and causing the top ends oi such to more in an outward;dire tion, against the n i e of adapted to be turned in ahorizontal from the driving spindle 5, throughbevel-- springs 18 which are-tending to normally hold the web-holders in toward the'ceuter oi the cylinder. A recess 19 is constructed in the cam-rin 18 within which. a'pin 20 attached to tl1e body,'.(see Fig. 2.) is adapted to enter and impart a turning movement to the cam-ring when the body is turned, the recess'19 being made s u'h'iciently long to allow a certain amount of play.

T he web-holders 12 .are formed with a hook 21 at or near the middle of their length which fits upon a wire ring r22 that extends around the top of the slotted member 6 of the cylinder. By this arrangement the webholders. 12 that areheld by separate springs 18 are entirely independent of each other, with regard to both movement and control.

The cylinder 6 rests upon a fork shapedmember 23 that is hingedlysecured to the body-holder 1'andis held in a variety of different positions by a rod 24 that is attached .to the forked-member 28 at its lower end and is supportedjat its upper end by of afcam-disk- 27. Any turning movement shortroller or wheel 26 that issecurely attached to the rod and rests upon the edge of the disk 27 will have the effect of raising or lowering the forked-member 23and coirsequently the cylinder 6 that bearing upon it, andhas its result in tightening or slackening the" Work according to whether the cylinder is raised or lowered. Numbers are arranged upon the disk 27 to indicate the position of the difi'erent tensions.

The body 8 of the machine which is mounted in bearingsjupon the top of the body-holder 1 and'which comprises a circular shell having an internal. diameter large enough to'receive the lower cylinder 6 is lane gearing 28, when the machine is in use'l The upper portion of the body g which has a smaller inner diameter than the lower portion thereof and which is adj acent to the periphery of the lower cylinder (Sand forms a bearing. surface for -.the projections .or.

' butts of theneedle jacks, is formed with an approximately semi circula'if' shaped raised portion?!) such raised-portion being pro vided with surfaces 30 and 31 on its inner side that serve to'raise the needle jacks onto a higher plane -W lie L the bodyis turned.

Attached to the body 8' a position diamet- 'rically opposite the ralsed portion 29 is" the cam-box '32-.comprisi1ig an approximately semi-circular-shaped shell (see Fig.

7). Arranged upon the inside of'the cam box 32 are two' plates '33 and .34 provided. 7

with cam -surfaces 35 and 36 respectively,

which serve to ilnpart'the necessary move- .i

Arranged between the plates 53 and ill; is a special needle-picking device or needlelifter 39 (see Figs. 7 and 13) which is adapted to rock to and fro between. the plates Eli; and 34 as the machine is rcci tn'ocaled, when forming the heel and toe. The device is provided with a hinge-joint h) and pivotally secured upon a pin lltlnrt etx'lmnls througha bearing 42 formed in the shell to i the outside of the coin-hex where a lover til controlled by a spring 4.4,'issecnred noon it. The outer extremity of the needle lifting, device is formed with notcheswl?) extending in from each side in the manner clearly shown in Flo. 7, which serves to receive the leading needle as it pessesalongthe top of the plates 33 and 34t'ncc0rding to which direction the camhox is moving, when reciprocating. The needle will thus ronie in contect with the lifting device 39 and will rest within the adjacent notch 45, and as the retating action of: the cam-box continues-z the pressure of the needle against the lifting; device causes the latter to turn open its pivot and in doing so. describes an are and forces the needle upwardly within the groove of the. cylinder till it1'enchee the highest point ofthe are, at which level the needle will be held hythe spl'ingdmrnl 4(5 needlecylinder (lend lying within the recess 25.

This extending movement will have the ell'ecl oi causing the rockingilevice to plunge down were ward so as to press the needles contained within its recess down on tothe cam-sun face which forwards them into. action again. In order to bring the rocking-device into an. active position within range 61. the inactive needles, the position of which is shown in full lines Fig. 7, the end corners of the'lever are beveled oft so as to provide cam-faces 60*- clearly. shown in Fig. 1. A. plate 63 slidably secured upon the outside of the. cam-box 32 and is formed with a recess or cutaway-portion in its upper .edge to provide clearance for'the lever 60. An outwardly projecting stud or. pin 64; is

, arranged upon theplate at either end of" the recess, which, when the plate is moved toward it, will impinge againstthe cam-face 6 0 so .as to force the lever up a distance .suifibient to turn the rocking-device 55 with- ,in easy range of the. inactive needles. In

order to efiect the-movement otthe plate 63- automatically at every course the machine takes, a lever 65 is provided which is pivotally secured to the cain-box at or near the middle of its length. The upper end of the lever is attached to the-plate 63 by means ,of a pin-secured to the plate that extends u a throu h a slotted 0 enin in the lever 65.

l b ta upwardly through a hole in the flange of The lower end of the lever 65 is formed with a lug66 extending outwardly from its face, which, ,as the machine is reciprocated will strike against a tappet 67, so as to turn thelever upon its pivot and cause the plate 63 to move in the required manner. The tap pet 6,7 issecurecf upon a pin 68 that extends the body-holder 1 and is normally held down out ofrange of the lug 66 by a spring 69,( as shown in full lines Fig. 1), when the machine is'doing circular knitting, and is forced upward within range o1 the lug 66 '(as shownin dotted lines Fig. 1.) when the .Jnachine isdoing reciprocating-work, the t-appet being held in place by a, suitable catch 70 that engages the pin 68. The tappet is prevented from turning when the lug strikes against it by means of the springs 71 that extend outwardly from. the tappet inopposite directionaas shown in Fig. 1. Arranged also upon the outside of the cam- .box 32 is a stud/Z2 upon which is mounted a lever 73 in such a manner-that the lever will be-free to rock thereon and is held in the desired position by means of a suitable clip 74; held in' place 'by-aspring 75. At-. hitched to the lower end of the lever are two i horn-shaped-arms 76' and 77 that extend e0 I depressed by knocking it in by hand, the arm 7 6 is adapted to bear against the end of the lever 43 so as to lock it. and consequently away from the lever in opposite directions. When the upper end. of the lever 73 is the needle-lifting-device 39 in position, when the machine is d ng circular knit-ting.

\Vhen the lowefend of the lever 73 is depressed the other arm 77 is caused to depress a pin 78 (see Figs. 8, 22 and23), that is attached to the cam-plate 7 9 which is hinged within a slot 80 .formed in the shell ofthe body 8. Thecam-plate 79 will thus be pushed inward as shown. in dotted lines Fig.

23 in which position it is within range of the back needles, and will serve to raise them. on to a higher level, when the machine 1s reciprocating to form the heel and toe. ,7

When the lever 73 is again depressed at its upper end at the completion of the heel andtoe, the arm77 is thereby automatically knocked out of engagement with the pin 7 8 and the cam-plate 79 -is returned to its norma]. inactive position again by means of the spring 81 (Fig. 8).

The upper end of the lever 73 is suitably connected to three different cam-devices viz: a cam-plate 82 (Fig. 7) which servesas a knock-down-cam, by leveling the needles when doingcircular knitting; a cam 83 (Fig.

7) which serves to guide the latches of the rib needles on to a horizontally-arranged table 84 (Fig. 7) which table holds the latches into theproper position; and a cam 85. which serves to place the rib-needlelatches into position when the'selvage is being formed. The'lever 73 -is soconnected to each of these cams 82, S3 and 85 that when the upper end of the leveris depressed by hand, the three cams will be knocked into operation within range of the needles, when circular knitting is to be done, and in a similar manner they arethrown out of action when the lower end of the lever 73' is depressed, when reciprocating knitting is to -be.done. The cam 82 (see Figs. 27, 28', and

pin a, secured at the top of the cam-box 32 near one end. The plate dis so mounted on the pin e as to be capable of a small amount of vertical movement, but is pressed downwardly by a spring f surrounding the pin 6.

The plate pl isishaped as shown in dotted lines Fig. 2.9, and is provided at the end remote from the pivot with the cams 83. and

85. The cain 85- is secured to the end of the lever 12, while the cam 83 is formed on the plate 9 which is secured to the lever d by a screw h. Secured upon the top of the cambox underneath the ing the clip 74 whic is urged downwardly by the spring 7 5anchored at one end to'a lug pi ate (1 is a. plate a ha roviaeoo j on the plate 2' and at the other end to a pin is secured is secured to the level" 73, as .llOWn in Fig. 27, being broken away in Fig. 28 in order to show other details. it will be observed that in order to move the lever 73 from one side of the pyramidal shaped clip 74: to the other, the engagement of the correspornlingly shaped head of the lever 73 with the clip 7-; will bend the flexible plate i againstthe action of the spring 75, so that the plate i will press against the plate (Z which will be raised slightly. As the upper end of the lever 73 is pushed toward, or pulled away from, the :anrbox, the shipper m engages one or the other edge of the lever cl (see Fig. 27), and partially rotates it about its pivot and so moves all of the cams 82, 88, and 85 toward, or away "from the interior surface of the cam-box. It will be noted that when the upper end of the lever 73 is moved away from the cam-box so that its upper end remains on the left of the clip T l, all the cams lie close against the inner surface of the cam-box.

The table 84 before mentioned is arranged above a feeder 8G for the yarn to pass through, the feeder being adjustable to suit requirements. Attached to the feeder 86 15 an adjustable latch-'g'uide 87 (Figs. 1 and 7) of approximately semicircular formation, which serves to place the needledatches in their required order, when the machine is doing either circular or reciprocating work. A yarn carrier 88 is provided upon the outside of the cam-box 32, which moves with the canrbox and carries the yarn around the machine.

Referring now to the body 8 of the ma chine 1 and 8) 8'1) is the arched member or bridge wl'iich is formed with a hearing 90 in the middleoi? its length for an axle 91, (Fig. 2) that carries an upper or rib-knitting cylinder 92 and circular cam- .ferring device 97 which will be more arched member box 93, which are situated vertically in line above the lower cylinder and cam-box. The cylinder 92 is likewise arranged with needlegrooves 945 around its periphery to suit the class of work required and these grooves are arranged in line with the grooves of the lower cylinder. The lower ends of the 89 are connected together by an approximately sc'mi ciroular-shapcd shell 95 which envelops and is attached to the outer periphery oi the raised portion 29 of the body 8 before referred to.

'Pivotally mounted upon the outside of the semi-circular shaped shell 95 is a lever Elli (Figs. 8, 2d and 25) which is adapted to operate a transferring device 97, which, when in use serves to elevate the transfer needlcsin the lower needle cylinder t3 to the upper needle cylinder J2. The lilzcllltlifilrellerred to later on in the specification when to the cam-hon". A shipper m describing the operation of transferring, is held normally out oi range of the needles by llltflllS oi a spring 9S. The lever 96 while at the same time operating the trans l'crringdcvico 97, operates an upthrow-oam 99, which, when in use (as indicated by full lines l ipgs. 8, and 25) raises the transfernecdlcs on to lilo trunstcrriug'dcvice ill.

A. suitable doorway or opening 100 (Fig. 8) is cmistructcd in the raised portion 2t) of the body 21' and scmi'circular-shaped shell 95 which doorway serves to enable needles to be removed and replaced when occasion retpiires without having to otherwise dis turb the niachiiw. in order that the opening will not inlcrlicro with the working oil" the machine by causing a break in the nccdlc-rznre, it is provided with a suitable bridge'piccc 101 while the block 102 adapted to lit within the doorway serves to keep the nctnllcs in place within the grooves of the cylinder, a suitable swing-clip being, provided to hold the block in place.

llrl'crling; once more to the top cylinder rrt'eizrt-nce being; made to Fig. 2 of the drawings. a feature of its construction is the provision. made for adjusting: it to any desired tension. 'lhosc means comprise a ring 103 which tits within the lower end of the cylinder in the manner clearly shown in Fig. The riup; 1,0 3 adjustable from the top of the axle [)1 by means of a screw 10 t which is countersunk within the top end oi. the axle and engages with a shank 105 that extends down through the hollow of tbe'axle where it is attached by lllt't\ll-i of a screw 'lOti The top portion ot to the tension rinpi033. the axle Ell is incl ted by a collar 10? which rests upon the top oi the bridge 89. The collar it)? is conncclral to the attic by a setscrcw .lllti which enters a hole in the axle and serves to hold it in place. A. plate 109 rests upon the top end at the c: coding downwardly through the plate is a screw lit) which enga .S the head of the screw 104. The latter screw is prevented from moving up and down without prevent-- ing it from turning by means ot a pin ill which passes through the axle J1 and enters a groove or channel ll). extending around the periphery ol the head of the screw 104:. Arranged upon the inside face of the up per cam-box 93 is an approximately semicircular horirontal guide-plate 1125 (Figs. 2, 3 and 4t) which is adjustable from the on side of the cam-hora by means ()f'PlilS llel and 115, wuich are connected to the guide plate 113 and. extend through slotted openings 'll-l' formed in the shell of the box. 'llhe plate is held in its desired position by means of s iringtg'clips 1th and HT which ongage the pins iii and '2 respectively. The plate il serves to guide the needles into their desired position in the uuinncr which will be a'lterwaial ulnlcrstmid'. Constructed collar l0? and in the inner periphery of the canrbox at the back of the plate 113 is a recess 118 which receives a cam-plate 119 that throws the transfer-needles down on to a top-transferring-device 120 when transferring the needles from theupper to the lower cylinder. The cam-plate 119 is thrown in or out of action from the outside of the box by means of a pin 121 that is attached to the plate and extends through a slot 122 formed in the cam-box, and is" held in place by a spring clip 123. Arranged horizontally above the adjustable plate 113 is a fixed guard-rail 124: which serves to guard downthrow-cam125 which is operated from the outside of the cam-boxby means of a plate 126 that is slidably mounted upon the cam-box and which is. connected to the cam 125 by a pin 127 that extends through a slot 128 in the box, the plate being held in place by a spring-clip 139 as shown. The downthrow-cam 125 operates in conjunction with the top-transferring-device 120, and serves to guide the needles into place when in action. Provided also within the inner'iace of the cam-box 93 are two welting-cams 130 and 131- which operate in conjunction with. the guideplate ll3, a nd are hinged at 132 and 133 respectively, to the cane-box, and are adjustable from the outside of the ma chine by means 01" pins 134 and 135 that entend through a slotted opening 136 in the box, and are secured to a plate 137 slidably mounted upon the outside of the carmbox.

The plate 137 is held in the lower position (as shown in full lines Fig. 6) or in the raised position (as shown in dotted lines Fig. 6) by means of a spring-clip 138. A cam-plate 1 39 adjustable'froni the outside '40 of the cam-box by pins 140 and 1 11- serves to place the needle-latches upon the horizontally arranged table '84 in the lower cam-b0 32. Arranged above this cam-plate 139 is another. guide-rail 142 which is provided at one end with a door 143 which is adapted to hinge upwardly (as shown in dotted lines) to permit the needles to'p'ass through on to a stitch-cane 141 and to close so as to serve as a bridge and act in conjunction with the 54} welting-canis 130 and 131 before referred to. I The stitch-cam 1414 is adjustable from the outside of the cam-box by means of a pin 14-5 .and seives to regulate the stitches of the dial-needles, while a suitable helping cani 55146 which is placed between the stinh cam 141 and. the welting-cams l30'and 131, and

is adjustable by means of a pin 1&7, serves to regulate the formation of the loops. A

'7 bridge 148 is hinged to the top end of the 0 cam 146 and serves to cover the gap between the earn 146 and the welting-cams aforesaid,

' so as to guide the needles across. Arranged above the stitch-cam 1 14 is a guard-camplate 149 whichserves to keep the needles upon their path,

' heel and toe.

Secured to the lower edge of the cam-box are guide-plates 150 and 151 (Fig. 4) which serve to guide the needles into their proper position. during action. Likewise to the lower cam-box .32, a doo'rwa gor opening 152 is formed in the box, which will give access to the top needles, a filling block-being provided to keep the needlesanpl-aca- Attached to the upright portions of the} arched-member 89 before referred to, is; a;

latch-guide-plate 153 and needle jackguidw plate 154 respectively, the 'forrnelf'serving toprevent the latches of the cylinder-needles from closing after coming 'up throu gh the loop, while the latter prevents the back top needle-jacks from] engagin the lower needles when the 'jacks-arelii ted out of ac tion when setting. the machine to form the Extending dhwnxthrough the top portion of the arched member 89 is apin 155 which I is adapted to engage with the top carn-box so as to serve as aI-driving-pin.when. doing ribbing work, and to be heldup out of engagenient with the top cam-box'by aspring 156 when the machine pi s doing plain knitting.

To set the machine to knit a plain sock with a. oneand-one rib top, the needlejacks 203 which are fully illustrated in Figs. 14k to 19, are placed in the needle-cylinders in the following manner, reference being made to Figs. 29 and 21: The lower cylinder 6 (Fig. 20) is provided with a long-butttransfer-jack (Fig; 15) and short-butt-stationary-jack (Fig. 19) alternately arranged in the grooves of the front half of the oylin der, while a long-butt-transfer jack .Fi 14) and. a sho-rt-but-t-stationary-jack (Fig. 18) are alternately arranged in the grooves 1 5 of the back half of the cylinder. The jacks in the back halfcoi the cylinder are provided with a lower-short-butt as clearly shown, which the lifting-cam 79 (Figs. 22 and23) H engages, when forming the heel and toe. The long butt oi. the transfer-jacks performs the duties of knitting,transferring-and =-dividing as will beunderstood later onwhen the operation is explainedL-i Referring now;-

to the top cylinder 92 (Fig. 21.);the arrange-- 1:15- ment of the jacks is as follows: one-butts; transfer-jack (Fig. 16) then a vacant groove, two-butt-transfer-jack ig. 1'?) 1- then another vacant groove, one-'butttrans= ferfiack (Fig. 16),' a vacant groove-,-two butt-transfer-jack (Fig; 17 a'vacant green and so on all around the cylinder. The top- E butt oi these jacks serves to .knit,.transfer,-; and divide, while the lower-butt is not used a i at all in doing one-and-one rib and only-.123? serves to forward the jacks onto the-trans-.:-' w

'lhe arrangement of the cylinders is now cylinder with a needle engaged, and every all ernnite jack in with at needle engaged, lhe empt' y .loweneylirider-jacks being; in opto the needles in the top cylinder. The arrangement; of the top eylinder being, n needle H1 every nl-ternn-te groove,

while the other alternate grooves remain empty to allow the needles that remain in the lower cylinder to enter when the machine isin :trtinn. The operation is then continued by throwing the weltingrains 130 and 3:31 up out of action (as shown in dotted lines Fig; 6). This nioveinenl throws the needles in the top cylinder out oi action and leads them on to the pulh jlfornn-id by the plate 113, @{Hit'ifidfllii 1.42.,briklge .1 13, ruins 144 and M6, and they remain on this psuth tbi l'l the selveg e is tr mmed, the necessary number of roun 8 being: determined by l'he operutor who has iegrnrtl to the size oi work required.

At; the some time the won 83 (Fig. 7) "is serving to hind the latches of the top cylinder-needles upon the table "84-, while -t;he cam NFL-(Fig. (i) is serving to lift, them. The table 84; holds theylnt'ehes in e horizontal position 01 the iiveder St; to curry the yarn i-ntothe hooks of the needles. "When the latches drop off tl'ieend ol': l hei-t' zlble 8 they are caused to a! use on the-yarn in -tl1e books so as to form n toop in lhensnirl manner. A-fterthe onenndnne".rib topis formed, the needles in the lop eylinder are transferred back again into the; lower cylinder by throwing tihe dowmthrow7mm 119 (Fig. 4) intonation, \vhieh will guide the butts of the needlenn-las on to the t'rnnsierring-deviee 120 which inmrnhzs in precisely the same manner as the lowersirinisi'errinwdevice 97, the operation oi? which has nlreiuly been fully explained. 'lthe needles are thereby passed down into The I the lower cylinder again where they are re ceived by the empty transfer-jacks, after which the down-throW-cam 119 is thrown out of action again asis also the top cam-box itself by removing thedriving-pin 15-5. 7

I The top cam-box is left in a position with the guide-plate 113 '(Fig. 4) at the back of the machine, the plate being lifted up .out

of action so as to allow the back needlesof the lower cylinder to force the jacks in the upper cylinder outof the way when themachine is: forming the heel and toe. When this has been done the leg of the WOI'k iS finished in plain knittingby the' lower-cylinder-needles. The machine is'then set for forming the heel. This is done by'dep'ress' ing the lower end of the lever'73 so asto.

cause the'cams 82, 83 211161 85 (Fig. 7) to be pulled back out of action while thee-rm 7 6 'L-disengages the lever 43 so as to. unlock the needle-lifting-device 39 inside the cam-box.

The action also by means; of the arm 77 throws the lifting-cam '79 .(-Figs. 22 and 23) within range ofthej'needles. The machine is then turned so as to cause the lifting-cam 7 9 to liftup all. the needlesat theback of the machine out of action so"that' only ap}.

proximately one half off't'h'e ,needles remain in action as is .customary whenforinin I the. heel and toe. This.l1: tting action 0 the back-needles .forces. the back jacks oft/he top cylinder up in their grooves aslto-allow sufficient clearance. for ".thelower, 'needles.-

The positionof the machine when ready for reciprocating is thus; 1The'- lower cam box is at the back of the machine, the bridges 37 and 38 .(Fig; 7) resting upon the came surfaces 31 and 30 respectively sofas to form a horizontal path upon-.whioh the butts of the needle-jacks rest. .The machine isth'en' reciprocated until the heel isiitormed, theoperation of which vhas'alread ,"been exnlained. The lever 73 is' -then' epres'sed at its upper end so as toagain'thro'w the cams 82, 83 and 85 (Figz fifinto action.andto throw the lifting-cam 79igsgg22and23) out of action. The foot is their formed by the circular knitting and the toe is finally formed by reducing and increasing the numsame manner as the her of needles in the heel is formed.
